Summary: This study evaluated histamine formation in tuna by reproducing several storage conditions. The results showed that histamine was mainly formed in contaminated tuna samples and its formation rate was slower at lower temperatures. It was also found that using histamine-contaminated equipment for food handling could result in histamine formation in food.

Summary: Food spoilage leads to waste and diseases. A miniature sensor based on poly(styrene-co-maleic anhydride) was developed for on-demand spoilage analysis via mobile phones. The sensor was embedded in packaged chicken and beef to monitor spoilage. This low-cost, miniature wireless sensor can help consumers and suppliers detect spoilage of protein-rich foods and prevent food waste and food-borne diseases.

Summary: Biogenic amines (BAs) are food contaminants that can cause poisoning or allergic reactions. Common BAs found in food include histamine, tyramine, and putrescine. The number of poisoning cases related to BAs in food has increased, emphasizing the need for BAs detection to ensure food safety. Various analytical techniques and sample treatment methods are used for BAs detection.

Summary: This study screened three strains from different regions of Inner Mongolia that have the ability to degrade biogenic amines (BAs) in meat products. These strains can degrade various BAs, especially tryptamine and phenethylamine. They can be used as starter cultures in meat products due to their good fermentation capacity and strong ability to reduce BAs.

Summary: This study investigated the molecular mechanisms involved in histamine release by neutrophils in response to allergens in allergic patients. The activation of PI3K, MAPK p38, and ERK1/2 signaling pathways were found to be crucial for allergen-induced histamine release, with some contribution from the phosphatase calcineurin. Common therapeutic drugs and allergen-specific immunotherapy were shown to inhibit histamine release through different mechanisms, providing potential new targets for controlling histamine production.

Summary: Recognizing familiar conspecifics is crucial for social interaction, and disruption or potentiation of histaminergic neurotransmission affects short and long-term social recognition memory differently. Histamine is essential for the consolidation of long-term memory in social recognition, while impairments in short-term memory may be related to H3 receptors' function as heteroreceptors on cholinergic neurons.

Summary: Histamine derived from Th2 cells plays important roles in nasal allergic disorders by promoting Th2 cell infiltrations in response to antigen exposure. The production of histamine from Th2 cells is specific to these cells and not observed in Th1 cells or naive CD4 T cells.

Summary: A low-histamine diet is currently the most advised strategy for preventing the symptoms of histamine intolerance. However, there is great heterogeneity in the type of excluded foods among different studies, with fermented foods being the only unanimous exclusion. Approximately 32% of excluded foods have high histamine content as a likely explanation.

Summary: Seafood is an important source of nutrients, but it can be contaminated and cause foodborne illnesses such as scombroid fish poisoning. Histamine-forming bacteria (HFB) in fish muscles and tissues can produce histamine, with Gram-negative HFB being the major contributor to histamine accumulation in seafood. Various methods are available to detect and identify HFB and histamine metabolites, including rapid test kits for early detection. High hydrostatic pressure and irradiation treatment can prevent HFB proliferation and deactivate histidine decarboxylase (HDC) activity, with some sustainable methods like enzymatic degradation and electrolyzed oxidizing water being studied. Further research is needed due to different reactions of HFB to these treatments.

Summary: This study investigated the growth kinetics of foodborne pathogen B. cereus during the commercial production of liquid egg yolk using PLA(2) treatment. The results showed that B. cytotoxicus NVH391-98 can grow prolifically at 50 degrees C, with estimated minimum, optimum, and maximum temperatures of 16.7-18.5, 47.8-48.1, and 52.1-52.4 degrees C, respectively. The dynamic model was validated with isothermal curves and it was found that holding the temperature below 15 degrees C or above 55 degrees C can effectively prevent the growth of B. cytotoxicus in egg yolk.

Summary: The infection mechanisms of Arcobacter are still uncertain. This study found that Arcobacter isolates from food and water sources were able to adhere and invade Caco-2 cells, and carried at least two virulence markers. A. butzleri showed higher virulent activity compared to A. cryaerophilus, while A. lanthieri, A. skirrowii, and A. vitoriensis exhibited even higher adhesion and invasion values. Sewage isolates were more adherent and invasive, and had a higher gene content. The association between cadF and hecA with high adhesion capability was identified for the first time.

Summary: Interactions between bacterial species in the formation of dual-species biofilms in the food industry are affected by environmental stresses, such as temperature and pH. This study found that the combination of cold and acid stresses significantly increased biofilm formation, and different temperatures resulted in variations in the presence of specific bacterial species and the secretion of extracellular substances. The findings provide valuable insights for addressing mixed biofilms in food processing under diverse stressful conditions.

Summary: The study found that CpxAR TCS is an important regulatory mechanism for the virulence of C. sakazakii. Mutants showed weakened adhesion, invasion, and survival ability, and exhibited attenuated virulence in animal models. In addition, CpxAR TCS is involved in regulating the expression of genes associated with bacterial virulence and cellular invasion.

Summary: This research investigates the role of flagella-related genes in the adhesion of E. coli O157:H7 and the effects of certain cations on bacterial adhesion and motility. The results demonstrate that flagellar-mediated motility is critical in the early stage of adhesion, and the presence of Fe2+, Ca2+, and Mn2+ affects the adhesion and motility of wildtype strains but not flagellar function-impaired strains. These findings provide new insights into the mechanisms of bacterial adhesion and have implications for the development of anti-adhesion agents.
